Evie possessed an extraordinary choreographic brilliance, but an unexplained psychological mental link allowed her identical twin Chloe to mirror every original combination she conceived. Chloe exploited their mother's blatant favoritism, debuting Evie's routines ahead of her and branding Evie a pathetic copycat. On regional championship night, Evie collapses from acute heart failure alone in her locked bedroom, calling out for help.
Sensing her sister's agony through their psychic bond, Chloe feigns a medical emergency at the auditorium to stop their parents from driving home, demanding Evie transmit the routine's final sequence before she expires. Evie dies alone, returning as an ethereal apparition visible only in mirrors. Stripped of the link, Chloe's plagiarism collapses, culminating in a tearful public confession where Evie completes her final dance.
